Junos® OS Installation and Upgrade Guide
Performing System Backup and Recovery for a QFabric System
Supported Platforms QFabric System
Many routers and switches require an administrator to recover the software package and
the configuration file for the device separately. In the case of a device failure, this means
the administrator might need to perform two separate tasks (if neither the software
package nor the configuration file can be recovered).
In contrast, the QFabric system uses a unique mechanism that saves the backup and
recovery files for both the Junos OS software and the system configuration into a single
collection. The following QFabric system backup and recovery mechanism simplifies
and streamlines the recovery process so you can return to normal operations as quickly
as possible.
To backup and recover your QFabric system:
1.
(First time only) Implement the following one-time procedure to prepare your QFabric
system to use the system backup and recovery feature:
•
Insert a Juniper Networks software installation USB flash drive into the master
Director device. (This drive was provided to you as one of the components of your
QFabric system shipment.)
• Issue the request system software format-qfabric-backup command. The contents
and format of the USB flash drive are copied to the Director group shared directory
and are used as the basis for all future backup and recovery operations.
